Im horrible at this :( sorry about it being bold .. it wont unbold

How do you evaluate the following limits

1) lim x----> 3 [ ( l x-3 l ) / ( x-3 ) ]

2) lim x --->4/8 [ ( 3x^2 + x - 4 ) / (3x + 4 ) ]

3) lim x--->1 [ (x^2 + x -2 ) / ( l x -1 l ) ]

4)lim x--->-1 [ ( 2x^2 +5x + 3 ) / (x+1) ]

5) lim x---->0 { [ x+8] ^ 1/3 -2} / x
